WEBM to FLAC
Extract the soundtrack from WEBM video as FLAC audio. Everything runs on your device, so even large files never leave it.
From
WEBM (.webm)
To
FLAC (.flac)
Advanced options
FLAC is lossless, so there is no bitrate to choose — the audio is stored at full quality.
- Only the soundtrack is kept — the video track is discarded, which makes this much faster than a full conversion.
- Converting to FLAC cannot restore detail that WEBM already discarded — it only stops further loss.
- Conversion uses the audio and video codecs built into your browser, so results depend on your device. Unsupported targets are greyed out.

Private by design — no upload, no sign-up
This WEBM to FLAC converter runs locally, using your own browser. Your files are never uploaded to a server, so they stay on your device from start to finish.
- Are my WEBM files uploaded to a server?

- Is there a file size limit for WEBM to FLAC?
- There is no imposed limit, because nothing is uploaded. The practical ceiling is your device's available memory, so very large files may be slower on older hardware.
